Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a base structure for a ridge of a horizontal thatched roof that uses metal roof plates in a horizontal orientation, and particularly relates to a base structure for supporting a wrapping member. And the fixing structure of the top of the roof plate in the ridge.

[0002]

2. Description of the Related Art In a building having a normal floating roof, most of roofs having a roofing plate made of metal as a roofing material have a metal structure above a purlin or a roof, and a metal roof Being thatched is done using. And in such a structure of a building with a roofing structure made of metal, a main building is formed in the worship part of the roof, and the wrapping member is used as the final finishing member in this part so that the roof can be closed and rained well. It is completed and the top edge of the roof is fixed.

A conventional example of the structure of a metal sheet horizontal thatched roof will be described with reference to the sectional view of the ridge of FIG. 5. Reference numeral 1 indicates the roof as a whole, which is formed on the upper surface of a steel truss or a reinforced concrete slab, and on the upper surface thereof. When the roof is made of metal and is used sideways, the purlin 2 is supported horizontally and the slack 3 is supported in the gradient direction. The tartar 3 is formed in a hat shape, for example, and the wood board 4 made of wood wool cement, which is formed to have the same thickness as the height of the tartar 3, is dropped in between the constant intervals.
The bottom plate 4 is supported on the lower side flange of the tartar 3. A waterproof sheet 5 such as asphalt roofing is stretched on the upper surface thereof, and a metal roof plate 6 is engaged with the upper edge 61 and the lower edge 62 of the metal roof plate 6 on the upper surface of the roof sheet 6 while superposing the roof sheet 6 between them. A lateral thatched roof is formed by stretching.

In the roof 1, the building 7 is
Wooden base members 72 are arranged on both sides of the apex 71 forming the worship portion in the direction of the ridge, and the base members 72 are fixed with screws 73 at each pitch of the barrel 3. A waterproof sheet 5 is stretched on its upper surface, and a ridge wrapping member 7 is provided so as to cover the upper surface.
Attach 4. Both side edges of the ridge wrapping member 74 are bent downward to form a hanging portion 75, and the lower end edge thereof is bent along the roof surface to form a drainage 76. On the other hand, the roof plate 6 is raised in order from the bottom, and the uppermost roof plate 6 forms a rising portion 63 on the upper edge 61 along the side surface of the wooden base member 72, and is fixed by screws 64, The hanging portion 75 of the ridge wrapping member 74 covers the fixing portion from above and is fixed in common by the screw 64 or by another screw, and the drainer 76 overlaps with the upper portion of the uppermost roof plate 6.

Next, another conventional example of the structure of a thatched roof is shown in FIG. The sectional view of the ridge in FIG. 6 is similar to the previous example in the general structure of the roof, and showing the difference from the part of the ridge 7, the base of the ridge 8 in this example is entirely made of metal and forms a worship part. The base member 82 is arranged on both sides of the top 81, and the base member 8
2 is a ridge support portion 83 in the central portion and side edge support portions 84 on both sides.
And is bent and formed integrally with the intermediate fixing portion 85, and the fixing portion 85 is fixed at every pitch of the barrel 3 using the screws 86. The waterproof sheet 5 is stretched on the upper surface, and the ridge wrapping member 87 is attached so as to cover the upper surface. Both side edges of the ridge wrapping member 87 are bent downward to form a hanging portion 88, and the lower end edge thereof is bent along the roof surface to form a drain 89. Roofing board 6
The structure of the uppermost stage is substantially the same as that described in the example of FIG.

[0006]

One of the difficulties in the conventional base structure of the ridge of a metal sheet thatched roof is that, depending on the scale of the roof, the width of the main ridge formed in the ridge is given a large or small ratio. And that the apex angle θ of the ridge changes correspondingly with the change in the gradient, and both of these are points that require bending work on site. For example, the standard slope 3/1
Even if it is zero, even if it is a gentler or steeper slope, the stage specified on the drawing and the stage implemented on the site after the production may not match each other in the end, so that it has to be constructed by on-site processing. . Also, if there is a change in the apex angle θ,
The position of the screws is changed according to the height of the base member, the position of the rising of the uppermost roof plate with respect to the scale of the ridge is also changed, and the final size of the wrapping member supported by these base members is also changed. There is the inconvenience of being on-site.

A further serious difficulty is that the upper edge of the uppermost roof plate requires a start-up process in the field along the side surface of the base member, which is a lateral connection of the roof plate. In the section, it covers the roof plate material, the joint material, and the waste plate.Because these members have vertical ribs, the shape collapses due to bending work, and the fastening work is extremely difficult. Not only there, but multiple,
This is because water retention parts are formed over a wide range and cause corrosion.

[0008]

In view of the above problems, the present invention intends to improve the structure of a ridge of a thatched roof by using a metal roof plate in a horizontal direction and stacking it vertically. A ridge that was created for the purpose of forming a ridge at the top of the roof surface and finishing this part with a wrapping member when using a metal roofing board on the roof surface sideways. In the base structure of the base part, the base support members that support the wing wrapping member are made of metal and are located at each lap interval, and the central main body part hinged on the top part and the longitudinal direction of the main body part. It is configured by a telescopic portion on both sides that is slidably and slidably and fixedly engaged with, and the telescopic portion is supported by fixing the leg sides of the outer end to the upper surfaces of the slacks on both sides of the ridge. Auxiliary plates extend outward from the outer surface of the side part and are fixed to both sides from the hinged part on the top of the ridge. Top portion to the end portion of the auxiliary plate is characterized in that it is covered by the ridge wrapping member.

[0009]

[Operation] Therefore, according to the present invention, a ridge is formed on the top of the roof surface, and a base member for the wrapping member is installed in this portion, so that the wrapping member is supported. The base supporting member is a four-piece structure in which the main body in the central part of the ridge and the stretchable parts on both sides of the main body that support the fixed parts on the laps are fitted in the longitudinal direction of the main body. By slidingly and fixedly engaging with each other, it is possible to expand and contract according to the width of the main ridge formed in the ridge. Also, because the main body is rotatably supported at the top of the ridge, even if the main body changes in design or construction angle,
The expansion and contraction is adjusted between the main body and the expansion and contraction part, and the fixed part on the slack does not affect the position of the expansion and contraction part.
When the base member supports the building wrapping member, the building wrapping member does not require on-site processing.

Further, in the expansion and contraction portions on both sides, a sufficient accommodating portion is formed on the lower surface of the one-way auxiliary plate between the hanging portion of the auxiliary plate formed on the outer edge and the front surface of the leg side portion. , The upper edge of the topmost roofing board can be fixed on the surface of the slap using an ordinary suspension.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the support structure for the ridge of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing the ground structure of the ridge portion of the present invention on one side of the ridge, and FIG. 2 is a perspective view thereof. Reference numerals in FIGS. 5 to 6 are common to corresponding members. In the figure, 1 is a roof made of a metal roofing board 6 which is a thatched roof, and a tartar 3 is shown on the upper surface, and a wood board 4 of wood wool cement board between the tartars 3 and an asphalt roofing on its upper surface. The waterproof sheet 5 is shown in a partial cross-section, and the metal roof plate 6 has an upper edge 61 and a lower edge 6 not shown.
A lateral thatched roof is formed by tensioning between the slacks 3 while engaging and superposing them with each other.

1 and 2, in the ridge 8 of this example, the metal support members 10 of the present invention are arranged on both sides of the top portion 81 forming the worship portion. Support member 10
Corresponds to the width and spacing of the slack 3 and has central main body portions 20 and 20 whose main portion is a hollow hollow steel material, and is slidably and fixedly inserted by being inserted in the longitudinal direction of the main body portion 20. It is composed of four members, that is, the stretchable portions 30 and 30 on both sides to be fitted together, and these are base members that support the ridge wrapping member 40 in a shape that is folded up from the upper surface of the barrel 3 by a predetermined dimension. The main body portion 20 has a long hollow square steel material as a main portion, and a top portion 21.
The angle can be adjusted by attaching the hinges to both sides of the ridge. Hollow part 2
Reference numeral 2 includes an upper and lower surface 23 and a side surface 24, and the side surface 24 is provided with a slot 25. In the main body portion 20 of the present invention, when the members on both sides of the ridge are joined at the central top portion, this portion is hinged so that the apex angle θ is variable according to the slope of the roof. However, the pivot portion 26 is not rotatable, and both sides of the opened legs are held by friction so as to correspond to a predetermined angle, and when the main body portion 20 is set above the top portion 81, it is kept in a chevron shape. The leg opening angle is determined so that the expansion / contraction part 30 can be positioned on the ridge.

The expansion / contraction part 30 is composed of a sliding part 31 which is fitted in the hollow part 22 of the main body part 20 and is slidable inside the hollow part 22 and a leg part 32 fixed to the lower end thereof downward. The lower end of the leg portion 32 is bent outward to form a fixing portion 33 on the slack 3. A bolt 34 with a washer is attached to the side surface of the sliding portion 31, and the bolt 34 serves as the groove 2 described above.
When the elastic portion 30 is tightened and loosened through the sliding portion 31, the elastic portion 30 is fixedly and slidably connected to the main body portion 20 to form the elastic support member 10.

At the upper part of the leg part 32 of the expansion / contraction part 30, an auxiliary plate 35 is attached so as to extend the upper surface outward, and a part 36 of the upper surface is cut and raised as shown in FIG. The extension portion 38 is formed by engaging with the mounting slit 37 on the base end side of the auxiliary plate 35. The extension part 38 fixes the fixing part of the upper edge 61 of the uppermost roof plate 6 in a space surrounded by the front surface of the leg part 32, the lower part of the auxiliary plate 35, and the hanging part 39 at the tip of the auxiliary plate 35. It becomes the accommodation section 38 that accommodates,
It is possible to enable a normal fixing method on a rafter without forming a rising portion on the roof plate 6.

As shown in FIG. 2, the support member 10 formed by the main body portion 20 and the expansion / contraction portion 30 is formed as a piece and supports the ridge portion at each position of the slack 3 and is shown in FIG. As shown, a reinforcing base plate 4 defined by the building width is erected and fixed between the support members 10, and a waterproof sheet 5 is stretched, and then both side edges of the support plate 10 are sufficiently extended from the tip of the auxiliary plate 35. Let it hang. Here, the main body portion 20 and the stretchable portions 30 on both sides,
A ridge wrapping member 40, which covers the entire width of the ridge and the width of the ridge, is attached as a final finishing member.

The ridge wrapping member 40 includes a main body portion 41, a side edge portion 42 fixed to the hanging portion 39 of the auxiliary plate 35 by a screw, and a draining portion 43 further bent outward from the lower end thereof. The wing wrapping member 40, when supported by the support member 10 configured on the slack 3 according to the above, includes the main body portion 20 of the support member 10 and the elastic portions 30 on both sides,
Since 30 and 30 are configured to be slidable and fixable, they can be covered without requiring on-site processing simply by fixing the side edge portion 42 to the hanging portion 39 after adjusting the expansion and contraction of both.

Next, the roof plate 6 is raised in order from the bottom,
The upper edge 61 of the uppermost roof panel 6 is fixed on the downstream side in the housing portion 38 formed in front of the expansion / contraction portion 30, and a rising bending process along the base portion of the ridge is unnecessary. As the upper edge 61 and the hanging member 9 attached to the upper edge 61, those having a normal structure are used as they are. Also, the suspension 9
The installation position of is selected as far as possible from the accommodation part 38 and fixed independently, and is not restricted by the support member 10.

Of course, the support structure for the ridge portion of the present invention is not limited to the above embodiment, and for example, the main body portion 2
The cross section of 0 and the expansion / contraction part 30, especially the shape of the hollow part 22 may be downward C-shape, and the lower surface side may be opened. Further, as another modification, the fixing means for the slack 3 can be changed while leaving the sliding and fixing structure of the main body 20 and the expansion / contraction part 30 unchanged. In the example shown in FIG. 3, a fixing means on the slack 3 is provided at the lower end of the main body portion 20, and the expansion and contraction portion 30 is slidably fixed only with respect to the main body portion 20. That is, the leg portion 27 is fixed to the lower end of the hollow portion 22 of the main body portion 20 downward, and the lower end is bent to form a fixing portion 28 on the slack 3 and mainly by the screw hole 29. Corresponding to the size of the main wing, the fixed position on the barrel is selectively determined and supported according to changes in the apex angle θ. On the other hand, the expansion / contraction part 30 does not form the leg part 32 for supporting from the upper surface of the slack and ends with the hanging plate 32a at a position corresponding to the tip of the auxiliary plate 35, so that the accommodating part 38 can be stored. It differs from the previous example in that the formation is directly performed by the sliding portion 31.

Next, the example shown in FIG. 4 shows another embodiment in which the main body portion 20 and the expansion / contraction portion 30 are slidable and fixable, and the main difference from that of FIG. Is the elastic part 30
Is inserted into the inside of the main body portion 20 to slide, and the sliding portion 31 is formed in a pipe shape and inserted through the through hole 27a provided in the leg side portion 27 of the main body portion 20. Hole 25
That is, the expansion / contraction part 30 moves forward and backward without forming the groove, and the sliding part 31 is fixed from the outside of the side surface 24 by the set screw 34a. In this example, the structure of the main body portion 20 is changed with respect to the sliding movement of the expandable portion 30. That is, as described above, the hollow portion 22 has the downward C shape, which facilitates the assembly and processing of the guide member 22a for sliding the sliding portion 31. The guide member 22a forms a guide space only by a pipe externally inserted into the sliding portion 31 and a plate material (left half portion) that supports the pipe from the inner surface side of the hollow portion 22 or an inner end portion of the plurality of plate materials themselves. It is shown by the one that does (right half) and is obtained with a simple structure.

Further, in each of the embodiments, the basic roof construction itself is such that the suspenders 9 are fixed to the slacks 3 by means of pre-attached screws and fixed to the roof plate 6, but as a general mounting screw. Use a self-tapping screw to adapt to changes in inclination and ridge width, and adopt a fixing method that does not use screw holes, centering, or nuts.

[0021]

The supporting structure for the ridge of the horizontal thatched roof of the present invention is
When using a metal roofing board sideways on the roof surface for thatching,
In the base structure of the ridge when a ridge is formed at the top of the roof surface and this part is finished by the wrapping member, the base support member that supports the wrapping member is made of metal at every loose interval. The main body part is located at the top and is hinged at the top part, and the elastic parts on both sides that are slidably and fixedly engaged by being inserted in the longitudinal direction of the main body part. It is supported by fixing the leg side of the end to the upper surface of the slack on both sides of the ridge, and an auxiliary plate extends outward from the outer surface of the leg side and is fixed, both sides from the hinged part on the top of the ridge. Since the upper surface of the auxiliary plate up to the end is covered with the ridge-wrapping member, the support member of the ridge-wrapping member is composed of four members, so that the vertical angle of the ridge and the design can be changed. Even if there is a discrepancy between construction and construction, the size as a predetermined support member is secured, However, when the ridge wrapping member is attached to the ridge part as a final finishing member, it does not need an interlocking structure between the ridge wrapping members and can be attached to only the side edges by covering the supporting members, and their relative positions can be adjusted. Unaffected by change. In addition, since the supporting member is made of metal, it has excellent durability and not only eliminates the weak point of aging, but also forms the upper edge accommodation part of the roof plate on the lateral lower surface side of the expandable part. , It is not necessary to form a rise on the roof plate, and therefore, even in a position where a horizontal connecting portion is formed, a difficult connecting work is avoided. Produce an effect.
